Package: x2goclient Version: 4.0.1.3
X2Go Client 4.0.1.3 for for Windows is bundled with PulseAudio 1.1. If you replace 1.1 with 3.0 or later (2.0 was not tested), the .pulse-cookie file is not created and therefore pulseaudio.exe either fails to start or repeatedly restarts.
The bottom line is that sound will not work in Windows X2go Client with these newer versions of PulseAudio.
The simple workaround is to run X2Go Client with PulseAudio 1.1 once and then exit x2goclient. The cookie will be present even after x2goclient is closed. Newer versions of PulseAudio can then use that cookie.
These are my full test results for what files are generated with different versions of PulseAudio. They were tested on windows 7 32-bit SP1 Professional (with all important and recommended windows updates installed.) "mothership-7-32" is my test VM's hostname.
Note that I tested PulseAudio 1.1 (and 1 or 2 newer versions) under Windows 8.1 64-bit Professional (with all important and recommended windows updates installed) and the results were the same.
1.1:
Under C:\Users\mike\.x2go\pulse\ :
.pulse-cookie
.esd_auth
.pulse
.pulse\mothership-7-32-runtime
tmp.Hp2820
tmp.Hp2820\config.pa
3.0
Under C:\Users\mike\.x2go\pulse\ :
.pulse
.pulse\mothership-7-32-runtime
tmp.Hp1572
tmp.Hp1572\config.pa
(Pulseaudio.exe does not appear to be running at all, but maybe what
happened under 4.99.2 is happening.)
4.0:
Under C:\Users\mike\.x2go\pulse\ :
.pulse
.pulse\mothership-7-32-runtime
.pulse\mothership-7-32-runtime\pid
tmp.Hp2656
tmp.Hp2656\config.pa
Also, windows complains that "pulseaudio.exe has stopped working". And
it does so repeatedly,.This suggests that x2goclient.exe keeps on
trying to restart pulseaudio.exe
4.99.2:
Under C:\Users\mike\.x2go\pulse\ :
.pulse
.pulse\mothership-7-32-runtime
.pulse\mothership-7-32-runtime\pid (keeps on being created and then
disappearing because pulseaudio.exe keeps stopping and starting)
tmp.Hp3716
tmp.Hp3716\config.pa
